Experimental study on fresh and hardened properties of concrete by incorporating fly ash, metakaolin and brick powder by partial replacement of cement for M40 grade concrete

The present dissertation is on replacement of fine aggregate, as metakaolin, brick powder & fly ash, in this present construction concrete world the natural resources are undergoes to depletion and wastage of various materials are increased day by day. The construction growth also increased due to the heavy population .in this present manuscript the various materials are used as fine aggregate and check the concrete characteristics at various curing periods and know the behavior of the concrete. In this present study deals with the strength properties of concrete by using flyash,metakaolin& brick powder as partial supplements for fine aggregate at 0,5,10,15,20 at various curing periods 7,28,56 days. The use of materials in cement concrete a) Materials will modify properties of the concrete b) Control the concrete production cost c) To overcome the scarcity of fine aggregate d) clever usage of waste materials

Fabrication and mechanical behaviour of limonia acidissima ash – silicon carbide reinforced AL2024 alloy matrix hybrid composites

In the present scenario, Aluminium metal Metrix hybrid composites are widely using for aerospace applications, transport applications and structural applications due to their desirable properties. In view of this, the present investigation was aimed to synthesized aluminum –silicon-agro waste based hybrid metal matrix composites.The present experiment was carried out to examine fabrication characteristics and mechanical properties of Aluminium hybrid metal matrix composite. In the present investigation, Al 2024 reinforced with silicon carbide (Sic) and Limonia acidissima ash for developing the mechanical properties. The composites were synthesized by the stir casting technique. The composites were synthesized by varying Limonia acidissima percentage of weight as 0%, 2%, 4%, 6% and 8%. The mechanical properties of Tensile strength, Yield strength, the percentage of elongation, hardness were performed. The microstructural study was carried out by SEM examination.

A survey on rectangular patch antenna using a various shaped patch antenna

Microstrip patch antennas are most commonly used in dense, conformal and low- cost wireless applications because of the advantages over the traditional antenna. In this paper, the small introduction of microstrip antenna along with various patch shapes are discussed in detail. Numerous techniques are used to improve the parameters such as bandwidth, return loss, gain, and efficiency of the antenna. In this paper, different feeding techniques such as coaxial cable, line feed, Aperture coupled and proximity coupled feeding techniques along with their advantages and disadvantages are discussed. The formulas used for calculating length and width of patch and ground antennas are provided. The antennas with different slots on patch such as Triangular slot, E shape, Single U shape, Double U shape, fractal techniques are discussed.

Teaching English in multilingual classroom

The objective is to energize the understudies about getting the hang of, talking, perusing, composing, and fathoming English. Keep the counsel in this article as an instrument to be utilized frequently, and you will be one bit nearer to that objective. Students in a multilingual class are making different mistakes in structure and pronunciation. When you are a TEFL-guaranteed English educator, your vocation can lead you in numerous ways, including monolingual or multilingual classrooms at home or abroad. Below are a range of strategies that UW instructors use to help international, multilingual, and all students succeed, including Facilitating communication, encouraging participation, setting expectations for and responding to student writing, and supporting academic reading.

Smart electric fence the WALL-E

People living in rural areas of Sri Lanka are facing difficulties as wild elephants who in forest reserves entering villages. These wild elephants attack people and destroy the properties of villagers. The dump yards, garbage management areas and cultivated lands are attracting elephants for food. Elephants enter into the village from the nearby forest in search for food. The government has created the electric fence to prevent elephants from entering the village. Elephants break the electric fence and enter the village making these efforts useless. Elephant attacks have increased over the years killing humans as well as elephants. This system can predict and take precautionary action in order to minimize elephant attacks. Our systems are composed of automotive electric fence using light sensor and Thermal sensor. The light sensor will activate the fence when the sun goes down and the thermal sensor will detect the elephant and activate the fence during the daytime. When the elephant breaks the fence and enter, laser sensor will activate the siren. By geo point location system (GPS) technology, control room officer can view the exact place where the fence was breached. Data mining was used to predict wildlife officers about the areas where attacks are happening mostly. This system is beneficial for officers as well as villagers to prevent elephant attacks and save human and animal lives.

Improving the throughput of IoT devices for smart cities

Device-to-Device (D2D) communications and applications are expected to be a significant part of the Internet of Things (IoT). However, conventional network gateways reported in the literature are unable to provide sustainable solutions to the challenges posed by the massive amounts of D2D communications requests, especially in the context of the IoT for smart cities. In this paper, we present an admission control model for D2D communications. The model differentiates all D2D requests into delay-sensitive and delay-tolerant first and then aggregates all delay-tolerant requests by routing them into one low-priority queue, aiming to decrease the number of requests from the various number of devices in the IoT for smart cities. Also, an admission control algorithm is devised on the basis of this model to prevent access collision and to improve the quality of service. Performances are evaluated by the network calculus, numerical experiments, and simulations show that the proposed model is feasible and effective.
